is 2,869 billion kilometers. Its size is
four times larger than the Earth. It
turns on itself in 17 hours and 50
minutes.Uranus has 29 satellites.The
blue color of Uranus is the result of
the absorption of red light by
methane in the upper atmosphere.Its
maximum distance from Earth is
3
157 million km.
The atmosphere of Uranus, although composed
mainly of hydrogen and helium, contains a greater
proportion of water ice. Uranus is the planet of the
Solar System whose atmosphere is the coldest, its
minimum temperature being -224 ° C. Like other
giants, Uranus has a ring system with many natural
satellites. However, terrestrial observers and the
Hubble Space Telescope have seen signs of
seasonal changes and an increase in
meteorological activity in recent years.
